    A uniform circular array of isotropic sensors that stochastically dislocate in three dimensions—The hybrid Cramer-Rao bound of direction-of-arrival estimation 

    Wong, Kainam Thomas; Ndiku, Morris Zakayo; Kitavi, Dominic M.; Lin, Tsair-Chuan (Acoustical Society of America, 2019-07)
    An array’s constituent sensors could be spatially dislocated from their nominal positions. This paper investigates how such sensor dislocation would degrade a uniform circular array (UCA) of isotropic sensors (like ...
